• Consider the following:

Section 1 – Why study psychology?

• Psychology: the scientific study of behavior and mental processes

• Behavior: Any action that other people can observe or measure– Can be observed by another person (walking)– Can be measured through scientific instruments

(body functions such as heart rate; brain activity)

What are cognitive activities?

• Cognitive activity: Private, unobservable mental processes such as sensation, perception, thought, problem solving

What are psychological constructs?

• Psychological constructs – Concepts that enable us to discuss something that cannot be seen, touched, or measured directly

Goals of Psychology

• Observe and describe behavior and mental processes in order to better understand them

Theories, Principles

• Theory: Statement that attempts to explain why things are the way they are and happen the way they do

• *Often disproven and revised*

• Principle: a rule or law

• based on scientific research and empirical evidence – from observation, experimentation, or measurement

Psychology’s Past• Until the 1800s, psychology was not a

formal discipline

Roots from Ancient GreeceMore than 2000 years ago, Ancient Greece:

Socrates, “Know thyself”-Introspection: Look within

Aristotle- Associationism: Connecting new experiences to previously learned experiences

Ancient Greeks associated erratic, confused behaviors as the gods punishing people

Hippocrates suggested such problems were from abnormalities in brain

The Middle Ages

• During Middle Ages, most Europeans believed problems such as agitation and confusion were signs of possession by demon

• Test: Throw person into deep water; if they are pure, they will sink; if they are impure they will float and must die

*not 100% accurate

Birth of Modern Science

• 1500s-1700s: Scientific revolution ; scientific method;

• This approach led to the birth of modern psychology in 1879

Psychology’s Past• Wanted to describe, predict,

understand, and modify behavior

• They did not rely on empirical evidence – observations were often based on anecdotes or descriptions

Psychology’s Past – Good News, Bad News

• Good News – early thinkers not always wrong

–Ex.: Hippocrates – brain is the source of all pleasures

Psychology’s Past – Good News, Bad News

• Bad News – without empirical methods, mistakes were made–Phrenology: Different brain areas accounted for

specific character and personality traits–Graphology: One’s personality could be

revealed through handwriting –Astrology: Heavenly bodies influence human

affairs

Phrenology

Graphology

Astrology

Psychology’s Past

• Three early psychologies–Structuralism–Functionalism–Psychoanalysis

Birth of Modern Psychology• 1879 – First psychological laboratory –

Wilhelm Wundt (Germany) – first person to announce that he intended to make psychology a science –His field became known

as structuralism – Structuralism:

Breaks down experiences into objective sensations and subjective feelings

– Objective: Apple is round, red– Subjective: Apple tastes good; makes me happy

This is very basic; difficult to measure

Functionalism

• William James• interested in how and why things happen• Functionalism: how do mental processes help

organisms adapt to their environment? (What is their function?)• Adaptive behaviors (successful) are repeated and

become habits; Less adaptive behaviors are dropped

*Concentrated on mental processes, hard to measure (psychological constructs)

Behaviorism, John Watson

• Watson agreed with functionalism, wanted something more measureable

• Behaviorism: Study of observable behavior(Little Albert Study)

• B.F. Skinner agreed; he added the idea of ‘reinforcement’ to promote certain behaviors (tested on pigeons, rats)

Gestalt School

• Gestalt Psychology – school of thought that questioned how people interpret information

• They believe that perception is important and observable behaviors alone are not enough

Psychoanalysis• A theory of personality and a method of

psychotherapy, originally formulated by Sigmund Freud.– Emphasizes unconscious motives and conflicts

that occur during early childhood and were too threatening to remember consciously– Freud argued that conscious awareness is

merely the tip of the iceberg – the unconscious mind beneath the tip

Psychoanalysis• Freud concluded that

the unconscious mind contained unrevealed wishes, passions, guilty secrets, unspeakable yearnings, and conflicts between desire and duty• Many of these urges and thoughts are

sexual or aggressive in nature

Major Psychological Perspectives

• Biological Perspective• Learning Perspective• Cognitive Perspective• Sociocultural perspective• Psychodynamic Perspective

The Biological Perspective• emphasizes bodily events and changes

associated with actions, feelings and thoughts – how biology affects learning and performance, perceptions of reality, emotion

• This perspective involves:–Hormones–Brain chemistry–Heredity– Evolutionary influences

The Learning Perspective• emphasizes how the environment and

experience affect a person’s or animal’s actions

This perspective involves Behaviorism Social-cognitive learning theories

The Cognitive Perspective

• emphasizes mental processes in perception, memory, language, problem solving and other areas of behavior.• This perspective involves–Computer models of human thinking–Infant thinking–Intelligence testing.

Sociocultural Perspective• emphasizes social and cultural influences

on behavior• This perspective includes:– the study of rules, roles, groups and

relationships. – the study of cultural norms, values and

expectations.

Psychodynamic Perspective

• This perspective includes:–Unconscious thoughts,

desires, conflicts.

• emphasizes unconscious dynamics within the individual, such as inner forces, conflicts or the movement of instinctual energy.

Other Influential Movements In Psychology

• Humanist Psychology – emphasized personal growth and potential

• Feminist Psychology - analyzed the influence of social inequities on gender relations and on behavior of the two sexes

What do Psychologists do?

• Academic/Research Psychologists• Clinical Psychologists• Psychologists in Industry, Law, and other

settings

Academic/Research Psychologists• Research in areas of basic or applied

psychology.• Examples include:–Experimental psychologists–Educational psychologists–Developmental psychologists–Industrial/Organizational psychologists–Psychometric psychologists

Psychological Practitioners• Counseling psychologists help people deal with

problems associated with everyday life.• School psychologists work with parents,

teachers and students to enhance student performance.• Clinical psychologists diagnose, treat, and

study mental or emotional problems.
